77
Was my dads number back in the 50s when he built and raced dragsters. Got it by random when I started high school football. My niece who started racing go karts at 8 took the number. A year later my dad bumped into champkarts with it. I started racing in another class and took it. Eventually we all ended up racing champs together. The track owner and score tower agreed to let us add letters on. 77J , 77R and 77 K became our numbers respectively. J. Russ and Kristen. My niece moves up to super modifiers around 18 and retained the number there as well until she retired out at 22.
Sooo. 77 it is
